Theory On Engine noise

[brando]

Hello cousin Pedro - long time since we flew FB together mate! I'm glad to hear the CPL is going well

I didn't mean to suggest that the helmet would blot out the sound of the engine, far from it; more I was thinking that it would alter the ability to hear the various components and turn it into a continuous roaring sound.
I've just been reading pilot accounts of flying Hurricanes in the Battle of France and it's interesting to note the general comment on the sound of the gunfire when the button was pressed to unleash the 8 303's in the wings. All of them describe it a "crashing" sound, completely unlike the "taka taka taka" of popular fiction. Maybe it's because the latter is what gunfire sounds like from outside that it's often described that way.
Another popular comment was that sound also tied in very closely with what was being felt by the body due to vibrations through the airframe. One described "two bloody enormous explosions" behind him, combined with massive jolting sensations. He looked behind him, expecting to see that the back of the aircraft had disappeared, but it hadn't and he recovered and dived out to land across the Channel. Once down, inspection showed that the plane had taken two cannon hits only - one having hit a fuselage former and the other the armour plate behind his head! It's interesting to note that two cannon hits don't necessarily constitute a kill.

I read something just recently where a pilot make a comment about what you could hear in combat, and he said (something like)..."if you can hear their guns they are too close".

In IL2 now and always some people can hear other planes engines at kilometers as "sonic radar"

One of the big unsolved bugs in il2.

How possible is it?

As Oleg say:

"2. In Il-2 the sound engine was designed for HiEnd sound cards. It was so different sounding on Hi End and on regular cards.... On simple motherboard cards of some producers the panning was so simple, that we was unable to control it or regulate the distance... and some people begun to use it... In BoB we will have completely new sound engine that will not depending of type of sound card. We simply did own panning code, etc..."

If you like use this exploit google SoundExt.occlusions=0 or attenuation=0, afaik lots of squads know how to use, but dont like say to all community as logreaders etc.etc

PD. I hate exploits and dont use it

I thought this had to do with the "attenuation" setting in the config file?

Howdy Brando! Long time indeed, Im looking forward to fly a little more with you guys.

Surething, I wasnt meant to contradict you in my post, it was more towards Voyager, to share an experience =)


Interesting stuff you wrote. Ive read similar things too, pilots often talking about guns sound feeling close to the vib. in your body.

farewell, m8!

I had a hearing test a few months back, and apparently one of the tests for hearing damage uses a headset with a hard plastic foot instead of one of the phones, that they place on the back of your head, hard against the bone. It uses bone conduction, instead of the air conduction for the side with the hard foot, and if you can hear the hard foot better than you could with the speaker, that indicates one type of hearing loss.

So, even with ear protection, you're going to hear the vibration sounds, even if you don't hear the gas driven sounds. You'll get the banging of 12 cylinders and their assorted valves, but you won't necessarily hear the howl of the exhaust.

Now I suddenly wonder if pilots were hearing the firing of nearby rounds, or if they just hear the sonic booms as the rounds went past? I recall something about early investigations into the speed of sound being started by some infantryman wondering why misses cracked twice. Then again, when we're talking about machineguns, how do you tell the difference between the 2nd crack, and the 2nd shot?
